我已经设法addSubview:
在 UIAlertView 中/上设置了 UIProgressView,并为 ASIHTTPRequest 设置了所有内容,但是无论我把它放在哪里[request startSynchronous];
,它都会使应用程序崩溃。
[request startAsynchronous];
也无济于事。
谢谢。
这是我到目前为止所拥有的;
有一个检查文件是否存在等,这是有效的,但为了这个问题,我已经删除了它。
-(IBAction) update {
// define everything.
NSString *script;
script = [[[NSBundle mainBundle] bundlePath] stringByAppendingString:@"/myfile.txt"];
NSURL *url = @"http://example.com/myfile.txt";
UIAlertView *progressAlert = [[UIAlertView alloc] initWithTitle: @"Updating..." message: @"Please wait..." delegate: self cancelButtonTitle: nil otherButtonTitles: nil];
progressView = [[UIProgressView alloc] initWithFrame:CGRectMake(30.0f, 80.0f, 225.0f, 90.0f)];
[progressAlert addSubview:progressView];
[progressView setProgressViewStyle: UIProgressViewStyleBar];
ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
[request setDownloadDestinationPath:script];
[request setDownloadProgressDelegate:progressView];
[progressAlert show];
[progressAlert release];
[request startSynchronous];
[progressAlert dismissWithClickedButtonIndex:0 animated:YES];
}
